HAROLD XV. BROWN, OF SCHENECTADY, NEW YORK, ASSIGNOI- TO GENERAL ELECTRIC COlfIPANY, .A CORPORATION OF NEW 'YORK ELECTRICAL DISCHARGE DEVICE Application led July 20,

The present invention relates to electrical discharge devices and more particularly to devices of this character which are adapted to be surrounded by a jacket which is supplied with a cooling fluid. In the use of such devices some ditiiculty has been experienced in obtaining a goed electrical Contact with the anode member. Moreover, with the former clamping or contact member employed to secure t discharge device in the water jacket there has been a tendency to twist the disch@ device in the acket when the contact ne bers were tightening, thereby causing a twisting oit the leading-in wires, connected to the electrodes.

It is one of the objects of the present invention to provide an improved form of clamping and Contact member tor securing` a discharge device in a water aclet.

In carryingv the invention into effect 1 provide at diametrically opposite points on a shielding i, einher which constitutes a part of the water jacket two inoenendently adjustable clamping; members, which also fvnction as contact members, and make a sl' radially brushingh contact with the usual ternal flange on tie anode member of discharge device, rlhe clam the members may be separately tightened to any desired degree without cansing` twisting of discharge device *he water jacket, and each clamp will malte its own good Contact independent of the other. Moreover, on account of the radial brushimg` action, the contacts are self-cleaning.

rfhe novel eatures which l believe to be characteristic of the invention set forth with particulaii in the appended claims. The invention itslf however will best be understood f om reference to the following specification when considered in connection with the accompanying' drawing in which Fig. 1 is a view in ele i ti l f broken away, or" an electzical o..

jacket and discharge device; while lig. is a view of a cross section taken along line 5 5 in Fig. 2.

Referring more particularly to the drawing, l e indicated in Figs. 1 and Q a discharge device comprising an evacuated receptacle having a tubular glass portion 1 and tubular anode 2 joined to the glass member by a metal sleeve or collar 3 which is sealed to the @lass member at the point 4. The anode 2 is provided with an annular flange 5 which serves to support the discharge device in the water jacket. The jacket comprises a cylindrical member G which has a. relative y heavy dished shielding member 7 secured to the upper end thereof. The shield ing member 7 extends upwardly and outwardly beyond the seal l, serving in well lnown manner to protect the seal from corona or arc discharges, and is provided with a flan ge 8 which supports the flange 5 of the anode. A. suitable gasket 9 interposed btween the flanges prevents leakage of the cooling fluid.

The shielding member 7 is provided at diametrically opposite points with extensions or enlarged portions 10 and 11 which are bored out provided at their upper ends with screw threads 12. A pair oi independently adjustable contact or clamping members are positioned in the bore of the extensions 10 and 11, each adjustable member including a screw 13 which engages the threads 12. Screw 13 is provided with a pair of oppositely disposed lugs 11i which support a pivoted handle 15 between them. A bolt 16, screwthreaded at its lower end, extends through the screw 13 and engages a slidable member 17, the latter having a flattened contact surface and a cut-away portion 18 on its lower side. A pin 19 extends through the enlarged portions 10 and 11 ane` slidably engages the lower side of member 17 to prevent rotation thereof. A pin Q0 secures the bolt 1G to the sli dable member 17 that the bolt cannot turn but remains securely in place in member 1'?.

`When the pivot-ed handle 15 rotated so as to turn screw 13, the member 17 theclamping it securely in place. The sliding action of the member 17, in the radial direction of the flange 5, maintains the contact surfaces in a clean condition and has no tendency Whatever to twist the discharge device when the contact is tightened.

The cooling medium is suppliedto thewater jacket through an inlet pipe 21. An outlet pipe 22 is secured to the lower part of the shielding member 7 as indicated in Fig. l.

To prevent vibration ofthe discharge device, it is resiliently mounted on two rigid insulating supports 23 and 24 which are spaced apart and secured to a supporting bracket 25. Circular flanged plates 26 and 27 are mounted on the upper and lower sides respectively of the supporting members 23 and 24 and at the outer end thereof. These plates are provided with felt layers 28 and 29 re spectively on which are mounted two pairs of flanged members 30, 3l and 32, 33 which are similar to each other. A spring 34 is positioned between the upper Hanged mem ber 30 and the lower edge of the shield 7, while a similar spring 35 is positioned between the lower flanged member 33 and a flanged collar 36 which is secured to the lower portion of the water jacket 6 by an adjustable metallic band 37. As thus arranged the felt layers and spring supporting members prevent transmission of shocks and vibrations to the discharge device, the felt layers absorbing the higher frequency vibrations while the spring members absorb the lower frequencies.

What I claim as new and desire to secure by Letters Patent of the United States, is:

l. In combination, an electrical discharge device comprising an anode having a flanged portion, a acket therefor adapted to contain a cooling fluid, contact members slidably mounted in openings in the jacket and adapt- Y ed to engage the upper surface of the flange to secure the jacket to the discharge device, and means rotatably mounted in said openings for operating said slidable members.

2. In combination, an electrical discharge device comprising a flanged anode, a jacket therefor adapted to contain a cooling fluid, said jacket including a dished shielding member at the upper end thereof, said member having a plurality of openings therethrough, and means slidably mounted in said openings and adapted to engage the flange on said anode and thereby to position the discharge device in said jacket, and means rotatably mounted in said openings for operating said slidable means.

3. In combination, an electrical discharge device comprising an anode and a tubular glass member sealed thereto, a jacket surrounding said anode and adapted tocontain a cooling medium, said jacket including a dished shielding member and extending upwardly and outwardly beyond the seal bereaches tween said glass member and anode, said shielding member having a flanged portion adapted to support the discharge device, and means mounted in said shielding member and adapted to secure said discharge devicein said jacket, said means comprising a slidable contact member adapted toengage the anode and a rotatable member adapted to control the movement of said slidable member.

In witness whereof, I have hereunto set my hand this 19th day of July, 1928.

HAROLD W. BROWN.
